1 Claim.

The invention relates to a window construction of the general type wellknown in the art employing rubber strips or the like for holding theparts securely in assembled relation, but permitting the ready removalof the glass for replacement or for cleaning the inner faces of theglass panes, in the case of double glazed units. It has for one of itsprincipal objects the provision of an improved construction of the typespecified, wherein the rubber strips may be applied and removed veryeasily Without the exercise of any special skill, but which, at the sametime, gives the necessary security against displacement due to vibrationor loss of resilience. Further objects are the provision of a cheap,simple construction, applicable to a wide range of use and adaptable toexisting forms of devices, in which double panes are carried removablyin channel frames. Embodiments of the invention are illustrated in theaccompanying drawing, wherein:

Figure 1 is a side elevation of a car window embodying the invention.Fig. 2 is a section on the line II-II of Fig. 1. Fig. 3 is a sectionthrough one of .the rubber strips, showing its shape before itsapplication in the window. And Figs. 4 and 5 are sectional views throughmodifications, Fig. 5 showing another application of the invention tosingle glazed units.

Referring to Figs. 1 to 3, the demountable glazing unit in this casecomprises the panes 6 and 1. The frame therefor is made up of the tworeleasably interlocked metal angles 8 and 9, following the constructionof the Fox and Stroud Patent No. 2,054,856 of September 22, 1936, theangles being held in locked position, as in th'e patented structure, bythe wedges I0. When the wedges are removed, the angle 9 can be tilteddownward, so as to release the hook engagement at II, thus permittingthe separation of the angles and the removal or insertion of the glasspanes. The edges of the panes are spaced by the rubber strip I2, and arecushioned in the frame by the usual rubber channel I3.

The glazing frame, as above described, is seated in the sash I4, whichis formed with a rabbet to receive it, as shown, such sash beingprovided forward of the glazing frame with a channel I5, carrying therubber retaining strip I 6. The frame is cushioned in the sash by therubber angle I'I. Theflange I8 forming the front side of the channel I5,has its inner edge located, so as to provide a slight amount ofclearance with respect to the base of the frame angle 8 to permitinsertion of the frame into the sash open- (Cl. 2li-56.4)

ing as defined by the edge of the channel. The terms inner and outer andtheir variants, as used therein, have reference to locations withrespect to the center of the glass panes.

'I'he frame of the glazing unit is held in posi- 5 tion by means of therubber strip I6, which before insertion, has the cross section indicatedin Fig.

3, so that when forced into position, the lip i9 will bear strongly uponthe face of the frame. The strip, as shown, is provided with a lip 2U 10which ts over and covers the flange I8, the purpose being to give theconstruction a better appearance from the front and to add somewhat toits security. The strip is also preferably provided with a longitudinalgroove 2| for interlockl5 ing with the ends of the wedges 9 whichproject forward of the face of the frame, as shown, so as to form alocking rib on the frame which adds materially to the security withwhich the rubber strip is held in its channel I5 in the sash. The 20.thickness of the lip 22 of the strip I6 is such that it must becompressed in forcing it into its channel, so that considerablefrictional resistance is provided tending to prevent the accidentaldisplacement of the strip, after it is forced into 25 position. The useof the rib on the frame augments this resistance to accidentaldisplacement, rendering the anchoring of the strip very secure, evenafter the rubber has lost some of its resistance. While the use of thegroove 2| in the rub- 30 ber is desirable, it is not essential, as therib will, in any case, perform its locking function by seating itself inthe rubber due to the pressure.

The rubber may be applied in one strip extending clear around theWindow, but is prefer- 35 ably used in two sections in a window, such asthat of Fig. 1, the joints being shown at 23, 23. The frame members 8and 9 and the wedges I0, are also used in sections, the window shownrequiring a section for each straight side and one 40 for each curvedcorner. It will be apparent that the assembly consisting of the glasspanes and the metal frame may be readily inserted into the sash andsecured by the rubber strips, and on removal of thestrips, the frame canbe re- 45 moved from the sash and opened up for replacement or cleaningof the glass by removing the wedges.

Fig. 4 illustrates a modification, in so far as the frame constructionand sash construction are concerned, the rubber holding strips being thesame in shape and function, as thoss heretofore described. As in thefirst construction, the sash 24 is provided with a rabbet for carryingthe frame and has a channel I5 forward of the frame 65 and outwardthereof for receiving the rubber strip I6. The frame which carries theglas sbeet.is a channel made up of the oppositely facing angles 25 and26, whose base iianges are securediniixed rotation by a layer 21 of selfhardening material, such as sealing wax, sulphur, putty or low fusingmetal. In order to provide the locking rib for the rubber strip I6, thebase ilange 2l of the angle 25 is extended forward past the face ofthe'frame, as shown at 29, so that it performs the function of the endof the wedge Il in the oonstruction of Figs. 1 and 2.

Fig. 5 illustrates a modication, in which the glazing unit comprises thesingle glass pane 3|.A

The frame 3| is of rubber which has a recess or rabbet in which the edgeof the pane ts. The edge of the frame is extended tothe right of theplane of the face of the pane 30, thus providing the rib 32 whichinterlocks with the rubber holding strip 33. This strip diiIersprimarily from the strip I6 heretofore described, in that it lacks thelip 20. The frame 3| nts intoa rabbet in the sash 34, while the rubberstrip 33 lies in a channel 35 formed in the sash and located outward ofthe frame 3| and in front of the plane of the face of the pane 30. Thestrip 33 functions to hold the frame 3| in the sash in the same manneras the Broadly. -it is the xed portion of the wall immediately strip I1,the only diierencebeingthat then-rig Ilengagesandholdsbotbthepaneand itsframe,\ whilethestrip iiengagesandholdsonlytbe :trame of the unit.
